Sintering furnace facilitating waste heat recycling and utilization method thereof

Abstract

The invention discloses a sintering furnace facilitating waste heat recycling and a utilization method thereof. The sintering furnace comprises a circulating mechanism and a sintering furnace mechanism; the circulating mechanism comprises a first shell, a heat conduction pipe, an industrial fan, a second shell, an evaporator, a storage box, a third shell and a fourth shell; the inner side wall of the first shell is welded to the outer surface of the heat conduction pipe; and the inner side wall of the heat conduction pipe is welded with a flange plate of the industrial fan. Uniform heat conduction and oil gas purification are achieved through cooperation of related structures in the circulating mechanism; under a fraction technology of the evaporator, waste gas discharged by a waste smoke outlet of the sintering furnace mechanism can be fractioned into hot-state non-condensable gas and liquid-state sewage; the sewage falls into the storage box from the third shell under the action of gravity for water resource recovery, and the non-condensable gas flows back to a sealing sleeve of the sintering furnace mechanism through the gas conveying pipe to assist the sintering furnace mechanism in machining the next batch of workpieces, so that waste recycling of waste heat gas is finally realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection sintering furnaces, in particular to a sintering furnace which is convenient for reuse of residual temperature and a utilization method thereof. Background technique [0002] The sintering furnace refers to the special equipment for obtaining the required physical and mechanical properties and microstructure of the powder compact through sintering. The sintering furnace is used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the aluminum back field and grid wire sintering [0003] In the prior art, the sintering process is generally completed through a three-stage heating sintering device equipped with a preheating section, a heating section, and a high-temperature section.

Problems solved by technology

[0003] In the prior art, the sintering process is generally completed through a three-stage heating sintering device equipped with a preheating section, a heating section, and a high temperature section. However, in the prior art, a large amount of heat will be emitted to the outside during the fuel combustion process. In the environment, this will inevitably lead to a huge waste of energy, and will also increase the production cost of the enterprise; at the same time, this kind of hot gas is usually evaporated grease or production exhaust gas. If it is not treated, it will easily cause environmental pollution when it is discharged to the outside world. Simple access to the inside of the equipment will easily cause sintering crystals on the inner wall of the sintering furnace, resulting in equipment damage
